getasync exception in silverlight

Question

Hi guys i am trying to send getasync request with silverlight 5. the post async is working without any problem but the getasync throw that exception when adding authorization header. when not adding authorization header this is without exception just 401. what should i do to fix it?

the code:

    client.DefaultRequestHeaders.Add("Authorization", "Bearer secrettoken");

var getasynctask = await client.GetAsync("http://api.enteroption.com/api/UserDetails/GetUserIdByToken/");

the exception:

System.ArgumentException occurred

Are you adding the auth header with the post as well when it works? — Nkosi, Jan 28 '16 at 13:20

i know this is late but i struggled for quite a while with this getting my head wrapped the wrong way round .. but eventually i did the following and it worked, it really annoys me that this was the problem

  client.DefaultRequestHeaders.Add("Authorization", "Bearer " + kvp.Value);
  //client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", kvp.Value );
